As stated in the title. I have two sps that have grown from frags. The birdsnest in particular grew rapidly in my tank for months. My Poci has started to STN from the base (second time it has happened, the first time it recovered completely) and I noticed it might be happening to my birdsnest.
I read that sometimes shading can result in the bases dying off, but not sure this is the case. Tank is a 20 tall lit with two ai primes. No major changes recently other than the addition of a nepthea and some shrooms.
Params:
Salinity - 35 ppt
pH - 7.8 - 9 (always stable in this range)
Alk - 8.7
Cal - 430
Mag - 1430
Phos 0.9
NO3 - ~5
I know phos is high, but it has been stable in this range for months now, and birdsnest was growing consistently in this range. All other corals are growing, puffy, and generally happy/healthy.
Thoughts on possible causes? I am wondering if there is not enough flow reaching that side of the tank.. I have two koralia 240s on either side pointing at one another. (I recently added the second, but this was happening before that addition)
